Quantitative evaluation of fetal brain parenchyma volumetry (PV) and brain volumetry (BV) based on manual segmentations of high-resolution reconstructed fetal brain volumes for five randomly chosen fetuses from the database

	C3	C6	C11	C13	C16
PV (estimated) ml	52.42	37.16	365.74	126.87	307.49
PV (manual) ml	50.58	35.33	379.50	126.36	297.21
PV (% error)	3.65%	5.17%	3.62%	0.40%	3.46%
BV (estimated) ml	79.01	39.14	416.96	137.96	325.50
BV (manual) ml	77.17	38.45	416.00	133.49	313.17
BV (% error)	2.33%	1.76%	0.23%	3.25%	3.79%

The percentages of errors in PV and BV have been reported for automated volumetry as compared to the reference volumetry based on manual segmentation of the high-resolution reconstructed volumes
